Surface dc-current with\ndensity up to $\\textit{j}_{max} \\sim 10^{3}$ A/cm$^{2}$ results in break of\ninversion symmetry of Si and induces optical second-harmonic generation with\nintensity that corresponds to the appearance of dipole second-order\nsusceptibility $\\chi^{(2)d}(j_{max})\\sim 3 \\cdot 10^{-15}$m/V.",
